Influence of White Cement Content on the Performance of Decorative Mortar in the Presence of Microemulsion

Article Preview

Abstract:

The influence of white cement content on the compressive strength, flexural strength, tensile bond strength, water capillary absorption, anti-efflorescence and stain resistance of decorative mortar in the absence or presence of microemulsion were studied in this paper, meanwhile the effect of the microemulsion was analyzed. The results showed that the increasing white cement content increases the compressive and flexural strengths, reduces the water capillary absorption, and improves the stain resistance of the decorative mortar, but has adverse effect on the anti-efflorescence. While the tensile bond strength first increases and then decreases with the increase of the white cement content, and as the content of which is 7%, there appears a maximum value of tensile bond strength. The microemulsion improves the performance of the decorative mortar, particularly significantly enhancing the anti-efflorescence and stain resistance, except for the improvement of compressive and flexural strengths.
